I was a reactor operator on a submarine. Trained on the A1W in Idaho, operated an S5W in the fleet. Even cleaned the main sea water heat exchanger with Teflon rods to remove the barnacles inside.
Well then you know where waste heat goes. There’s nothing free. We trade power for fuel or something. The old S5G plant was interesting but the most fun I ever had was operating a hydro plant. Quiet, clean, and easy to take care of. Nice. Think about all the water vapor we sent into the air when we were hot. The aquifer isn’t endless and droughts take a toll. Bears watching what rich people think they don’t care about. IMO
